Well, first of all, I'm not convinced that P5 has poor quality. If anything, its better quality. Some folks expected more. As for creating in P5 and rendering in PP, the answer is pretty much no. The added features of P5 over the old PP are the dynamics and that's not backward compatable. I tried a pz3 made in P5 to see if it would open in P4 and unless you change the version number, forget it. I didn't try that. I think P5 is well worth the upgrade and I think CL will get sr2 going before too long.
